Aos Service Manager

IMPORTANT: this repo is archived and moved to https://github.com/aosedge/aos_core_cpp.

Aos Service Manager (SM) is a part of Aos system which resides on the device side and stands for the following tasks:

• communicate with the communication manager;
• install, remove, start, stop Aos services;
• configure Aos services network;
• configure and monitor Aos services and system resource usage;
• provide persistent storage and state handling for Aos services.

See architecture document for more details.

Prepare build environment

sudo apt install lcov libsofthsm2 libsystemd-dev
pip install conan

Build for host

To make a build for host please run:

./host_build.sh

It installs all external dependencies to conan, creates ./build directory and builds the manager with unit tests and coverage calculation target.

It is also possible to customize the build using different cmake options:

cd ${BUILD_DIR}
conan install ../conan/ --output-folder . --settings=build_type=Debug --build=missing
cmake .. -DCMAKE_TOOLCHAIN_FILE=./conan_toolchain.cmake -DWITH_TEST=ON -DCMAKE_BUILD_TYPE=Debug

Cmake options:

Option	Description
WITH_TEST	creates unit tests target
WITH_COVERAGE	creates coverage calculation target
WITH_DOC	creates documentation target

Options should be set to ON or OFF value.

Cmake variables:

Variable	Description
CMAKE_BUILD_TYPE	Release, Debug, RelWithDebInfo, MinSizeRel
CMAKE_INSTALL_PREFIX	overrides default install path

Run unit tests

Build and run:

./host_build.sh
cd ${BUILD_DIR}
make test

Check coverage

lcov utility shall be installed on your host to run this target:

sudo apt install lcov

Build and run:

./host_build.sh
cd ${BUILD_DIR}
make coverage

The overall coverage rate will be displayed at the end of the coverage target output:

...
Overall coverage rate:
  lines......: 94.7% (72 of 76 lines)
  functions..: 100.0% (39 of 39 functions)

Detailed coverage information can be find by viewing ./coverage/index.html file in your browser.

Generate documentation

doxygen package should be installed before generation the documentations:

sudo apt install doxygen

host_build.sh tool doesn't generate documentation. User should run the following commands to do that:

cd ${BUILD_DIR}
conan install ../conan/ --output-folder . --settings=build_type=Debug --build=missing
cmake .. -DCMAKE_TOOLCHAIN_FILE=./conan_toolchain.cmake -DWITH_DOC=ON
make doc

The result documentation is located in ${BUILD_DIR}/doc folder. And it can be viewed by opening ./doc/html/index.html file in your browser.

Install libraries

The default install path can be overridden by setting CMAKE_INSTALL_PREFIX variable.

Configure example with user defined install prefix:

cd ${BUILD_DIR}
conan install ../conan/ --output-folder . --settings=build_type=Release --build=missing
cmake .. -DCMAKE_TOOLCHAIN_FILE=./conan_toolchain.cmake -DCMAKE_INSTALL_PREFIX=/my/location

Install:

cd ${BUILD_DIR}
make  install
